Abstract
Zusammenfassung. Die vorliegende Arbeit berichtet erste Analysen zur Reliabilität und Validität sowie klinische cut-off-Werte der deutschen Bearbeitung der Social Interaction Anxiety Scale und der Social Phobia Scale (Mattick & Clarke, 1989). Die Skalen wurden 43 Patienten mit Sozialer Phobie, 69 Patienten mit anderen psychischen Störungen und 24 Kontrollpersonen ohne psychische Störungen vorgelegt. Die ermittelten Werte für die innere Konsistenz und Test-Retest-Korrelation sprechen für eine sehr hohe Reliabilität. Hinweise auf eine konvergente Validität ergaben sich aus hohen Korrelationen mit konstruktnahen Meßinstrumenten zur Sozialen Phobie, während die Korrelationen zu Depressions- und Angstmaßen erwartungsgemäß geringer ausfielen. Die beiden Skalen diskriminieren Soziophobiker sehr gut von Personen ohne psychische Störung und Angstpatienten, während die Diskriminationsleistung von depressiven Patienten geringer ausgeprägt ist. Die ermittelten cut-off-Werte liegen deutlich unter den amerikanischen Werten und sind als vorläufig zu betrachten. Insgesamt sprechen die Ergebnisse für den Einsatz der Instrumente als reliable und spezifische Screening-Instrumente für Soziale Phobie.
Abstract. The psychometric properties of a German version of the Social Interaction Anxiety Scale and the Social Phobia Scale (Mattick & Clarke, 1989) were evaluated in 43 social phobics, 69 patients with other disorders, and 24 normal controls. Internal consistency and retest reliability were very good and comparable to the original versions. Both scales showed high convergent validity as indicated by high correlations with other measures of social phobia. Lower correlations were observed with depression and anxiety measures. Social phobics were significantly discriminated from normal controls as well as patients with other anxiety disorders and depression, but not from patients with mixed anxiety and depression. cut-off scores were significantly lower than obtained with original versions and need further examination. To sum up, our results indicate that both scales are useful as reliable and specific screening instruments for social phobia.
